5.1 Ball bearings

Note!
The fans from Elektror are equipped with sealed
deep groove ball bearings, which do not require
relubrication.
Note!
Check the ball bearings during servicing and
prior to recommissioning.
Operation is only permitted with fl awless ball
bearings!
Note!
In the event of frequently starting up and shutting
down, premature replacement of the bearings
will be required. Determining the time for repla-
cing the bearings is the sole responsibility of the
maintenance and servicing personnel, who must
make a safety judgement.

Ball bearing change recommendation
- Prior to reaching the minimum service life
- 30 months following delivery at the latest
- Check after 6 months' storage time; change if necessary
5.2 Sealings and radial shaft sealing rings
For safety reasons, sealing components and radial shaft
sealing rings are to be replaced at least on every occasion
when maintenance involves opening, removing or altering
sealing elements in some other way.
5.3 Fine fi lters
The degree of soiling of the fi lter mats must be checked at
regular intervals, as appropriate to the environmental/de-
ployment conditions and, where applicable, environmental
protection requirements. That is, the owner must ensure that
fi lters are permeable.
5.4 Cleaning
There is a high risk of injury on the inside of the device due to
rotating parts during operation. Decommission the device in
all cases and wait until all moving parts have stopped before
opening, reaching in or inserting tools into the device.
Secure the device reliably against it being accidentally re-
started during the entire period.
Also make sure that no other dangerous situation can arise
when restarting after a standstill, e.g. as a result of a power
failure or blockages.
